TO ALL WHOM IT MAY CONCERN:

Bc it known that Tvc, ADOLPIIUS HOWARD, of Wellsville, county ofAllegany, and State of Nerv York, and GEORGE F. HOWARD, of the city ofChicago, county of Cook, and State of Illinois, have invented a new andimproved Machine for Washing Leather after having laeciiieinowcd fromthe vats; and we do hereby declare that the following is a full andexact description thereof, reference being had to thaceompanyingdrawings, and to the letters of reference marked thereon.

To enable others skilled in the art to make and use our invention, tvcwill-proceed to vdescribe/its construction and operation.

Figure I is a sectional elevation showing the brush and end of thewater-conduetor.

Figure II is a side elevation with the side removed showing the endsofthe brushes.

The nature of our invention consists in constructing an apparatus ormachine by which leather may be rapidly and successfully washed after ithas been subjected to the action of the tannin. It more particularlyconsistvs in providing two or more revolving brushes secured to shaftsor cylinders in arectangular frame. The said brushes are made to revolvetoward each other, and receive their motion from any of the Well-knownpowers. It further consists in so arranginga tank as to supply Water tothe leather as it passes through between the brushes. Both sides oftheleather are subjected to the action of the brushes at the same time,thus removinyin the most successful manner all the sediment remainingupon .the side of leather after it has'been removed from the vat. Thusby our invention a great amount of time and labor is saved, and the Workdone in the most perfect manner. v

Letters of like name and kind refer to like parts in each of thefigures.

O 'is a frame, rectangular in form, and enclosed with boards or othersuitable material, to which the shafts or cylinders P containing thcbrushes E E are attached, and made to revolve toward each other, runningin'suitable bearings secured in any convenient manner to the frame O. FF are band-wheels, to which the power may be applied to either, the saidband-Wheels being rigidly secured to the shafts or cylinder I so thatmotion is communicated from one shaft or cylinder to the other by meansof the cross-belt a, which passes around the band-wheels D D, or motionmay also be communicated from one shaft to the other. by means ofgear-wheels, in

which case the belt a may be dispensed with.k B B are water tanks, whichare located at each end of the frame O, or at any other convenient pointfor the purpose of supplying Water to the leather While it is beingsubjected to the action of the brushes, a conductor or pipe leading fromone tank to the other, so that both may be supplied with an equalquantity of water. I is a pump-log or tube, which is intended toraisethe Water to the tank, but is not fully shown, as it is no part oi'our invention. A is a dash-board, which extends above the top of themachine and back of the throat through which the leather passes toprevent the water from being spattered, and to guide the leather intothe machine. It Will be observed that the frame H is made in twosections, one above the other, so that access may be had to the brushesby removing the upper section of the frame.

The operation consists simply in passing the leather after it has beentaken from the vats into the machine, when it immediately comes incontact with the brushes upon both sides, and by the action of thebrushes the leather is drawn through the machine. At the same time itreceives an abundant supply of water from the tanks B B through theorifices, as seen in the drawing. It will be seen that as the brushesrevolve toward each other at a. speed of about one hundred revolutionsper minute, the leather receives the action of the brushes upon bothsides at the same time, thus facilitating the process of removing thesediment in the most and complete perfect manner.

Having thus described our invention, what We claim, and desire to secureby Letters Patent, is-

1. Two or more revolving brushes, or their equivalents., for washingor'removing the sediment from leather for the purposes and substantiallyas herein described.

2. n combination with the brushes E E, the tanks B B, or equivalents,for the purposes and substantially as herein set forth.
